MERRY-GO-ROUND.

SPECIFICATION forming part of Letters Patent No. 669,842, dated March12, 1901.

Application filed June 6,1900.

T0 ctZZ whom it may concern:

7 Be it known that I,W1LLIAM F. MANGELS, a citizen of the United States,and a resident of the city of New York, (Coney Island, borough ofBrooklyn,) in the county of Kings and State of New York, have invented anew and Improved Merry-Go-Round, of which the following is a full,clear, and exact description.

The invention relates to merry-go-rounds having crank-shafts forimparting movement to the seats; and the object of the invention is toprovide certain new and useful improvements in the construction ofmerry-go-rounds, whereby the driving-gear for the crank-shafts iscompletely relieved of the weight of the revoluble frame, andconsequently undue strain is avoided and the frame is supportedindependently of the gearing to insure an easy running of the machinewith comparatively little power.

The invention consists of novel features and parts and combinations ofthe same, as will be fully described hereinafter, and then pointed outin the claim.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a plan view of the improvement with the seats and otherordinary parts of the merry-go-round omitted. Fig. 2 is an enlarged planview of the central portion of the device shown in Fig. l and with partof the fixed gear broken out, and Fig. 3 is a sectional side elevationof the same on the line 3 3 in Fig. 2.

The improved merry-go-round is provided with a suitable central post A,on which is fastened a support B, having an annular ballhearing 0 forengagement with the under side of a frame D, mounted to turn loosely onsaid post as a center, said frame D being formed of suitableradially-extending beams preferably made in sections fastened together,the inner sections'of the beams being connected with each other bysuitable rings, as is plainly indicated in Fig. 1, the outer sectionsbeing connected with each other by con- Serlal No. 19,246. (No model.)

necting beams or braces, also fully shown in Fig. 1. The frame D isprovided with the usual pin or lantern Wheel E, connected with the powerfor rotating the frame in the usual manner.

On the revoluble frame D are journaled crank-shafts F, having the usualcranks F at or near their outer ends for connection with horses or otherseats mounted to rock on said frame and receiving a rocking motion fromthe crank-arms during the time the frame D is turned around. Thecrank-shafts F are arranged in pairs, and each pair is provided withgear-wheels G in mesh with opposite sides of a gear-wheel G, secured ona shaft G journaled on the frame D between the shafts F of a pair ofshafts, as will be readilyunderstood by reference to Figs. 1 and 2. Onthe inner end of each shaft G is secured a pinion G in mesh with a bevelgearwheel G secured to the center post A above the frame D, as isplainlyillustrated in Fig. 2. Now it is eXident that as the severalpinions G are in mesh with the fixed gear-wheel G a rotary motion issimultaneously given to all the shafts G when the frame D is turned, andthe rotary motion given to each shaft G is transmitted by its gear-wheelG to the gearwheels G on a pair of crank-shafts F, and consequently thedesired rocking motion is given to the horses or other seats during thetime the frame D is revolved.

By having the bearing for the frame D completely independent of thegearing for driving the crank-shafts F it is evident that said gearingis completely relieved of all strain incident to the weight of theframe, and consequently it requires comparatively little power to rotatethe frame D by the motor used for the purpose. Furthermore, all dangerof the gear-wheels binding is completely avoided whether the. frame isloaded to a greater or less extent.

It is understood that the pairs of gearwheels G in mesh with oppositesides of the gear-wheels G form, with the latter and the pinion G atrain of gear-wheels for rotating the crank-shafts from the fixedgear-wheel G when the frame D is rotated.

Having thus fully described my invention, I claim'as new and desire tosecure by Letters Patent- A merry-g0-r0nnd, comprising a central 5 post,an annular bearing secured to said post, a frame mounted to turn on saidbearing, a gear-wheel fixed to the post above the frame, crank-shaftsarranged in pairs on the frame,

a pinion-shaft arranged between each two of '10 a pair of shafts andhaving driving connection therewith, and a pinion on each pinionshaftmeshing with said gear-Wheel, substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

WILLIAM F. MANGELS.
